You are right it is illeagle to send a signal that is the same as X,K,KA,LASER, or whatever,but it is not illeagle for the PHAZER unit to receive the signal,then scramble it with noise.I know I have one,they will pay your tickets for 1 year,plus a 3 yr warranty on the unit itself.I know it works cause I have a couple friends of mine that are troopers that I tried it with,they tried all the bands ,including laser,they told me that the radar read 322mph, then 22mph,then ZERO.I have a speed trap about 100 yrds from my house, where they sit nailing people right & left,so I leave my unit on, and the cops haven't issued a ticket there in 3 months, it will mix the signal for 3 miles,but on the downside if you are less that 100 feet from the radar it is useless,but you should be able to see him way before that.You can buy either unit, jammer with radar detector all in one,$399.00, or if you already have a detector you can buy just the jammer for $199.00 in 3 month installments..
